HINGE Filed Sept. 29, 1958 2 Sheets-Sheet 2 LLOYD R. A NDERSON BY (1% v ATTORNEY IN VENTOR United States Patent 3,082,474 HINGE Lloyd R. Anderson, 6804 Millwood Road, Bethesda 14, Md. Filed Sept. 29, 1958, Ser. No. 763,962 Claims. (Cl. 16-167) The present invention relates to pivotal mounting of doors and more particularly to hinges for mounting a door in a manner so that the hinge does not loosen from the door frame or from the door. The present invention is a continuation in part of my prior application Serial Number 402,502 filed January 6, 1954, now Patent 2,853,747, and application S.N. 687,130 filed September 30, 1957, now Patent 3,021,554.

The hinge of the present invention includes some of the features of the prior application and additional features in the manner of mounting the hinge to simplify the mounting thereof and also includes the use of a pivot type hinge and the use of a floor mounted door closer so that the door will remain properly associated with its mounting structure.

An object of the present invention is to provide a door mounting including a floor closer for supporting a door in a manner that precludes loosening of the door from its mounting.

A further object is to provide a pivot type hinge which will not become loosened in ordinary use.

Another object is to provide hinge structure which may be mounted in mortise recesses or on the surface.

Another object is to provide a method of mounting hinges in accurate positions.

Other and further objects will be apparent as the description proceeds and upon references to the accompanying drawings, wherein:

FIG. 1 is a perspective of a closed door mounted on a door closer and non-loosening pivot hinge of the present invention;

FIG. 2 is a perspective of the top pivot hinge used in the mounting of the door of FIG. 1;

FIG. 3 is a transverse section through the pivot of the hinge shown in FIG. 2;

FIG. 4 is a fragmentary section taken on line 44 of FIG. 1 showing the mortise mount of the pivot hinge;

FIG. 5 is an enlarged fragmentary perspective of a portion of the door and door hinge leaf mounted on a floor mounted closer;

FIG. 6 is an elevation of the non-loosening pivot hinge mounted with its jamb hinge leaf plates surface mounted and the door hinge leaf plates mounted in mortise recesses of double depth, and showing the edges of the hinge leaves exposed on the outer surface of the door and frame;

FIG. 7 shows a non-loosening pivot hinge with surface mount of the jamb hinge leaf and a mortise mount of the door hinge leaf in double depth mortise recesses;

FIG. 8 shows a double mortise recess mount of the hinge jamb leaf and surface mount of the door leaf;

FIG. 9 shows surface and single depth mortise mounts of the hinge jamb plate and head jamb plate respectively of the jamb leaf, and double depth mortise and single depth mortise of the heel door plate and head door plate respectively of the door leaf;

FIG. 10 is an elevation of a multiple knuckle hinge with single depth mortise and surface mount of the hinge jamb plate and head jamb plate respectively of the jamb leaf and single depth and double depth mortise mounts of the heel and head plates of the door leaf; and

FIG. 11 is a perspective with parts broken away of multiple knuckle non-loosening hinge with an outside surface plate mounted on the outer surface of a door ice and single mortise mount of the hinge jamb and head jamb plates of the jamb hinge leaf in the frame.

Briefly, the present invention comprises a pivot type hinge comprising a jamb hinge leaf having a hinge jamb plate and a head jamb plate forming a dihedral for surface or mortise mounting in a door frame and a door leaf having a heel plate and a head plate forming a dihedral for surface or mortise mount in the heel and head end of a door with knuckle means fixed to the head jamb plate and head door plate and a pivot pin connecting the leaves. The hinge may be of the multiple knuckle type and be surface mounted or mortise mounted. In surface mounting any plate of one hinge leaf the corresponding plate of the other hinge leaf should be mounted in a mortise of double depth to avoid excessive clearance between a door and the door jamb. The invention also includes the use of a door leaf in combination with a door closer or pivot hinge mounted in the floor adjacent to a door frame with the door hinge leaf having a heel door plate and an end door plate forming a door dihedral hinge leaf to maintain the pivot axis of the knuckle means thereof in fixed relation to the door and to the closer, particularly with a pivot axis which is offset from the outer face of the door.

Upon more detailed reference to FIGS. 1 to 4 of the drawings, a door frame having a hinge jamb 20', a head jamb 21, and a lock jamb 22 receives a door 23 which is pivotally mounted by means of a top non-loosening pivot hinge 24 and a bottom door closer or pivot hinge 25 having a vertically extending shaft 26 which receives a hub 27 fixed to door end plate 28 of door dihedral door hinge leaf having a door heel plate 29 with the plates of the closer or pivot door hinge leaf being mortise mounted in mortise recesses in the door as clearly shown in FIG. 5 and being secured to the door 23 by means of screws 30 passing through countersunk openings in said plates. It will be noted that the bottom of the hub 27 is flush with the bottom surface of the end plate 28. The closer or pivot door leaf is secured to the shaft 26 by means of a key 31 of cylindrical shape having an upwardly tapering flat portion against which a locking screw 32 is tightened to maintain the hub and thereby the hinge leaf in fixed position on the shaft 26.

The door closer is of the type shown in Patent 2,501,505 and has the shaft 26 urged to door closing position.

To accurately locate the axis of shaft and the case 25 of the closer, the jamb leaf of the pivot hinge 24 is mounted in proper position and a plumb line 26A is dropped therefrom passingthrough the plumb line aperture 43 of the jamb hub 37, the plumb bob 26B thereon providing an exact point of reference for the location of the center 26C of the shaft 26 and after properly positioning of the case 2.5, such case is grouted or otherwise secured in permanent position.

The upper end of the door 23 is hingedly mounted by the pivot hinge 24 which comprises a dihedral jamb leaf having a hinge jamb plate 33, and a head jamb plate 34 forming the dihedral jamb leaf which is received in mortise recesses in the hinge jamb 20 and head jamb 21 of the door frame. A door dihedral hinge leaf having a heel edge plate 35 and a head plate 36 fixedly connected together is received in mortise recesses in the heel edge and head end of the door, the various plates being secured in position by conventional screws.

An outwardly extending lug projects from the head jamb plate and carries a first hub 37 while an outwardly extending lug on the door head plate 36 carries a second hub 38 providing knuckle means which receive a pivot 0 pin 39 providing pivotal connection for movement of the engages the pivot pin 39. The pivot pin is removably secured to the door leaf hub 38 by means of a locking screw 41 threaded into a transverse opening, the lower end of the bore of the door hub being covered by a set screw 42 threaded into the lower end of the pin 39. The upper end of the jamb hub 37 is closed except for a small threaded plumb bob cord receiving bore 43 which is closed by a set screw 44. A thrust bearing 45 may be provided for use when the pivot hinge 24 is used at the bottom of a door and such thrust bearing may be of the anti-friction type to reduce friction and reduce wear. With the present dihedral arrangement the pivot hinge may be used at both ends of a door.

FIG. 6 shows the jamb leaf of the pivot hinge 24 surface mounted on the inner edges of the hinge jamb 46 and head jarnb 47 of a door frame with the door plates 35 and 36 mounted in mortise recesses 48 and 49 respectively of double depth.

FIGS. 7. 8, and 9 show other possibilities of mounting the pivot hinge with various combinations of depths of mortise recesses and various surface mounts of the hinge plates, and with the plates received in mortises covering the edges of the plates when the plates are not surface mounted.

The following table using S for surface mount and l M for a single depth mortise and 2 M for a mortise of double depth shows various possibilities of mounting the various plates of the non-loosening hinge regardless of whether the hinge is of the pivot or multiple knuckle pivot type.
